Place the jars on a protected surface. Spray with black spray paint. You'll want to spray lightly and let dry; use several coats and let dry.

When the spray paint is completely dry, apply Mod Podge to a jar. Wrap the lace around and apply more medium until the lace is secure. Let dry.

Apply Mod Podge over the top of the lace to seal and let dry. Repeat with the other jar(s) and let dry before using.
